GAS-STOVE.

Specification of Letters Patent.

Patented Mar. 18,1913.

Application filed June 23, 1909. Serial No. 503,815.

The object of my invention is to producea-construction of stove or rangein which the bottom, and the means to ignite the burners (comprising aconduit or channel) are integral or are directly connected. I accomplish'this object by means of the device illustrated in the accompanyingdrawings, forming part hereof, in which- Figure 1 is a section on line1'-1 of Fig. 2. Fig. 2 is a transverse section of a stove or rangeshowing the bottom thereof in plan view. Fig. 3 is a section on line 3-3of Fig. 2. Fig. A is a front elevation of a range, open, showing amodified form, of ignitin conduit. view 0 the bottom of the oven,showing the modified form of igniter. Fig.6is a pers tive view of themodified form of igmter. Fig. 7 is a section on line 77 of Fig. 5.

Referring to said drawings, 1 designates -a fragmentary portion of arange or stove of the usual construction except-as hereinafter setforth. The said range is provlded with,

or comprises an oven 2 and a broiler 3 and the front thereof is adaptedto be closed by the door or doors 44. The said oven and broiler areseparated by means of the horizontally disposed wall 5 which constitutesthe bottom of the oven and the top of the broiler. Said bottom 5 hasformed therein a trough or depression 6 which-extends from the front ofthe range toward and terminates near the rear wall thereof as shown inthe drawings, the lower side or the bottom thereof at each side thereofis provided with downwardly projecting wings or walls 77 which inclosean open space or channel 8 which constitutes a conduit or channel toconduct or convey gas mixture emitted from the perforations aa of theburners 9-4) or from a ortion of them to the forward end of saidchannel, whereby the gas mixture escaping through the contracted portionb of said channel may be Fig. 5 is a perspective ignited, therebycausing the ignition of all the gas mixture escaping from the numerousperforations aa in said burners. The said downwardly projecting wings orwalls 77 at points immediately above the burners are provided withsemi-circularly shaped recesses cc into which the upper portion of theburner or burners project, and the rear end of said channel 8 is closedby the -wall 10. The depression ,6 does not perform any particularfunction other than to enable the ready production of thedevi-ce in themolding o eration. Vithout the depression 6 it would be somewhatdiificult to produce the downwardly projecting ribs by the ordinarymolding processes. The contracted portion b of the channel 8communicates with the pocket 11 formed in the plate 12 secured to thefront of the range between the o'venand the broiler doors. The saidburners are suppliedwith combustible gases in the usual manner, and thegas .and air are mixed in the usual manner and with the usual mixer. g

It is obvious that the downwardly projecting wingswhich constitutethegas igniting channel or conduit, instead of being integral with thebottom of the oven may be made separately therefrom as shown in Figs. 4to 7 inclusive. In said Figs. 4 to 7 is shown a range, in all respectssimilar to that illustrated in Figs. 1, 2 and 3. The bottom 5 having anopening 11 extending from-the front to near the rear thereof in thesides of which recesses k-k are formed to receive the lugs mm projectinglater ally from theupper sides of the channel 7 for the purpose ofsupporting the said channel or conduit as shown. The. said channel issupported upon the edges of. the

opening longitudinally made in the bottom so that the conduit may bereadily removed from the bottom, and in the event of breakage, theconduit could be supplied without necessitating the removal of theentire bottom as would be the case if breakage occurred when the conduitis integral with the bottom.

The advantage of the construction herein described over the priorconstructions in the art for similar purposes is that the bottom and theconduit are made integral or are capable of being directly assembled andthat the construction in no wise interferes with complete radiation ofheat, and on the contrary produces uniformity in the heat radiated fromthe burners to the bottom of the oven. It has also the advantage ofgreat simplicity in' construction.

Having described my invention what I claim and desire to secure byLetters Patent is .1. An igniting device for gas ranges includin an ovenbottom, having formed on its un er side downwardly projecting ribs, thesaid ribs co-iiperating with each other and the bottom of the oven toprovide a channel which leads toone side of the oven bottom, and aburner arranged under the oven bottom so that a portion of the gasemitted from the same will enter the-channel and be deflected thereby toone side of the oven bottom, where it can be readily ignited. v

2. An igniting device for gas ranges, includin an oven bottom having adepression w ich extends inwardly from one edge thereof and graduallybecomes deeper as it recedes fromthe edge, the said bottom beingprovided with downwardly projecting ribs extending along opposite sidesof the bottom of the depression and the said ribs cooperating with eachother and the bottom of the depression to rovide a channelwhich leads toone side 0 the oven bottom and has an upwardly and outwardly inclinedtop, and a burner arranged under the oven bottom so that a ortion of thegas emitted from the same w' 1 enter the channel and be deflectedthereby to one side of the oven bottom'where it. can be readily ignited.

3. An igniting device for gas ranges, including an oven bottom providedwith downwardly projecting ribs which cooperate with each other toprovide a channel leading to one side of the oven, a side wall for theoven formed with a pocket which establishes communication between theend of the channel and the interior of the oven, and a burner arrangedunder the oven bottom so that a portion of the gases emitted therefromwill enter the channel and traverse the same to the mouth of the pocketwhere-they can be readily ignited.

4. An igniting device for gas ranges, including an oven having a doorand formed with a bottom provided with downwardly projecting ribs whichcoiiperate with each other to provide a channel which leads to the'frontof the oven, a contracted neck leading from the forward end of thechannel to the interior of the oven at a point adjacent the oven door sothat access can be readily had tothe channel when the oven door is open,and a burner arranged under the oven bottom so that a portion ofthegases emitted therefrom will enter the channel and traverse the saidchannel and neck to the front of the oven where they canbe I the ovenbottom, and a burner arranged under the oven bottom so that. a portionof the gas emitted from thesame will enter the channel and be directedthereby to one side of the oven bottom, where it can be readily ignited.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.

ROBERT MUNRO. In the presence of- Cnaanncn A. WILLIAMS, JOHN H. Ronny.
